ADCS II Data Sheet.

Status Display

☼16:55 S1=29.8°CH

This is the normal display for the unit. If the unit is left displaying anything else for more than 1 minute without a key being pressed then it will return to this display.

Control period

The first character of the status display shows the current control period:-

☼ Day time operation (Moon symbol) Night time operation ▲Ramping up from night to day ▼ Ramping down from day to night

Current Time

The current time is shown next on the status display and is shown as Hours:Minutes. This will be 00:00 (Flashing) if the clock has not been set.

Current Temperature

The current temperature being measured by one of the sensors is shown next along with the sensor number. The display will constantly cycle round the available sensors showing each one for 15 seconds.

Eg. S1=20.8°C OR S2=85.5°F

If there is an alarm then an alarm indicator will be shown and the temperature display will flash.

S1▲32.6°C The temperature is above the high limit S2▼22.4°C The temperature is below the low limit S1F50.0°C The sensor probe is faulty (Short circuit) S2F0.0°C The sensor probe is faulty (Open circuit)

A flashing temperature display will be accompanied by the alarm LED flashing and an audible alarm if this is enabled. To silence the audible alarm hold ←, the audible alarm will then only sound again if the alarm reoccurs or a different alarm occurs. The alarm LED and display will continue to flash whilst the alarm condition is present.

Heater ON/OFF

The final character in the status display pulses to show the amount of power currently being supplied to the heater. If the unit is in pulse control mode then the indicator is displayed at the same time as power is supplied to the heater. If the unit is in dimming mode then the on/off period of the indicator will be proportional to the amount of power being supplied.

Minimum and maximum temperatures are available for up to the last seven days. The first part of the display shows how long ago and which sensor the display is for.

eg. -1S1▼24.8°C▲26.0°C

This display shows :-

-1 Yesterday (1 day ago) Note. No number is displayed for today’s display S1 The display is for sensor 1 ▼24.8°C The minimum temperature ▲36.0°C The maximum temperature

From the min/max temperature display

← Silence any audible alarm → Hold to reset current min/max to current temperature ↑ Go back 1 day (if available) or return to the status display ↓ Go forwards 1 day or return to the status display

Setting the time

From the initial status display press → to access the menu The display will show ‘Time 00:00’ (If the time has not been set). Press →, the first ‘00’ (Hours) will flash, use ↑ and ↓ to set the hours. Press →, the second ‘00’ (Minutes) will flash, use ↑ and ↓ to set. Press → again to complete setting the time. Press ← to return to the status display or ↑ and ↓ to check/set other items in the menu (See next section).

Menu

Each setting in the menu is shown as a message followed by its current value.

Whilst a setting is shown (not flashing)

← Return to the status display → Adjust the setting ↑ Show the next setting ↓ Show the previous setting

Press → to start adjusting a setting. The setting will now be shown flashing. Whilst a setting is flashing → Confirm the adjusted setting or move on to next part ← Cancel adjustment and return to original value ↑ Increases the setting (Hold to increase quickly) ↓ Decreases the setting (Hold to decrease quickly)

Control Period

The ADCS II has two temperatures at which it controls, one for the day time (☼Temp) and one for the night time ([moon symbol] Temp). The night time period can be controlled by either a time period, the light sensor or a mixture of both. The ☼Start and (Moon symbol) Start times define a period that will always be selected as day time, between these times day time control will always be selected. Outside of the this timed period the light sensor is used to determine day or night. Whenever the period changes from day to night the control temperature will ramp down from ☼Temp to (Moon Symbol) Temp over a period controlled by the RampTime setting. When the period changes from night to day the opposite occurs and the temperature ramps up.

To enable the night time drop function to be controlled completely by the light sensor set the ☼Start and (Moon symbol) Start times to times that will always be inside daylight hours (eg. 11:00 and 13:00).

To disable the night time drop function set the Light sensitivity to Maximum (Permanent ☼).

To make the night time drop function work on just the timer (Ignore the light sensor) set the light sensitivity to Minimum (Permanent [Moon Symbol] ).

When setting the light sensitivity the first character on the display shows what the sensor is currently detecting. It will change from (moon symbol) to ☼ as the setting is increased and from ☼ to (moon symbol) as the setting is decreased or if the sensor.

Additional Sensors

Up to 3 additional sensors may be fitted to the ADCS II by simply plugging them in at the back of the unit. Additional sensors should be fitted in order, so if you have just 1 additional sensor it should be fitted as sensor 2. The number of additional sensors fitted should then be entered in the menu. Additional sensors can be used with the fixed sensor to control at an average temperature or just used to monitor. If a number of sensors is used for averaging control then the first so many sensors must be used, so if 3 sensors are used for averaging then the fixed sensor (Sensor 1), Sensor 2 and Sensor 3 will be used.

Control Response

This setting allows the temperature control of the unit to be tailored to a particular environment. The setting varies from 1 to 7, generally the default setting of 4 gives good control. A lower setting could be used where the controlled space takes a long time to heat up or cool down. A higher setting could be used where the controlled space heats up or cools down very quickly.

IF the temperature never seems to reach the desired value and the heater is never at full power then try increasing the setting.

IF the temperature constantly seems to vary up and down around the desired value and the heater is varied from nothing to maximum then try decreasing the setting.

High limit cut-out

Normally the unit controls the power to the heater using an electronic switch (A triac) but an electromechanical switch (A relay) is also included as a back-up. If a sensor fault (On a sensor being used for control) or the cut-out temperature is exceeded then the unit will cut power to the heater using the relay (You will hear a click). If the temperature falls the relay will be used to supply power to the heater again. In effect the unit becomes an ON/OFF controller using the relay if the triac in unable to control the temperature for any reason. The high limit cut-out temperature can be set independently of the high temperature alarm so that the alarm can occur either before the cut-out operates or afterwards if the temperature continues to rise.

Power Failure

The ADCS II has a back-up facility that will allow the clock to keep time for a short period without mains power. During a power failure the time is displayed flashing and the alarm LED and beeper are activated for a short period once per minute. The clock will keep time without power for approximately 1 hour, after this period when power returns the clock will display 00:00 (Flashing). The other settings are stored in non-volatile memory and should always be retained.

12V Power Output

The 12V output terminals on the back of the unit can be used to supply power to an external device (eg. A small fan). The output can supply 12V at up to 250mA. To make a connection press on the small orange lever with a small flat screwdriver, insert the stripped end of your wire and release the lever.

Communications

The ADCS II is capable of communicating with a PC using an optional interface and software.

WARNING

The socket on the back of the unit is NOT an ethernet connection and should not be connected to an ethernet network under any circumstances. Please keep all packaging and proof of purchase for future reference.

The ADCS II has been designed to last for many years if set up and used correctly.
